foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1.Structure and Drafting Rules of Standardization Documents"
drafted.
This document replaces GB/T 30370-2013 "Guidelines for Primary Frequency Modulation Test and Performance Acceptance of Thermal Power Generating Sets", and GB/T 30370-
Compared with.2013, except for structural adjustment and editorial changes, the main technical changes are as follows.
a) The main technical indicators of a frequency modulation test are added (see 5.5);
b) Added a frequency modulation test condition (see Chapter 6);
c) Added a frequency modulation test requirements and methods (see 7.3 and 7.4);
d) Added the primary frequency modulation characteristic diagram of thermal power generating units (see Appendix A);
e) A frequency modulation test load condition and disturbance quantity configuration table is added (see Appendix C);
f) Modified a frequency modulation test analysis calculation table (see Appendix D, Appendix B of the.2013 edition).

Performance Acceptance Guidelines
1 Scope
This document specifies the main technical requirements and methods for the primary frequency modulation test and performance acceptance of thermal power generating units.
This document is applicable to thermal power generating units with a single unit capacity of 100MW and above, and thermal power generating units of other capacity levels.
Carry out.
2 Normative references
The contents of the following documents constitute essential provisions of this document through normative references in the text. Among them, dated citations
documents, only the version corresponding to that date applies to this document; for undated references, the latest edition (including all amendments) applies to
this document.
GB/T 26863 Terminology of monitoring system for thermal power station
DL/T 657 Acceptance test procedure for analog quantity control system of thermal power plant
3 Terms and Definitions
The terms and definitions defined in GB/T 26863 and the following apply to this document.
3.1
The speed of each generator set is adjusted by the speed governor of each prime mover, so that the driving torque varies with the system frequency.
[Source. GB/T 26863-2011, 6.29.1.5]
3.2
The primary frequency modulation regulation system is insensitive to the speed difference or frequency difference near the rated speed.
3.3
From the last time the speed difference or frequency difference exceeds the frequency modulation dead zone to the time when the unit load starts to change in the correct frequency modulation direction
time.
3.4
The allowable range from the last time the speed difference or frequency difference exceeds the frequency modulation dead zone to the last time when the unit load reaches the target value
within the time required.
3.5
Speed droop droop
The slope of the static characteristic curve of the steam turbine control system. Usually, the ratio of the speed difference corresponding to the empty load and full load to the rated speed
expressed as a percentage.
